Usage                REAL X,A,B,Y
Y=FNP_cauchy(A,B,X)
 
Description                
FNP_cauchy returns the value of the integral of the Cauchy probability density function with parameters a and b at x. This integral, P(x;a,b), is defined by the expression
which reduces to
 
 
B must be greater than zero.
 
P(x;0,b)
Errors
FNP_cauchy causes an HTBasic error if its arguments are not all of type REAL or if b is negative or zero.
